          The Schematic Search Diagrams operation is performed on the schematic
          service resource. The result of this operation is an array of Schematic
          Diagram Information Object.
  
          It is used to search diagrams in the schematic service by criteria;
          that is, diagrams filtered out via a where clause on any schematic
          diagram class table field, diagrams that contain schematic features
          associated with a specific set of GIS features/objects, or diagrams
          that contain schematic features associated with the same GIS features/
          objects related to another set of schematic features.
  
          Inputs:
              whereClause - A where clause for the query filter. Any legal SQL
                            where clause operating on the fields in the schematic
                            diagram class table is allowed. See the Schematic
                            diagram class table fields section below to know the
                            exact list of field names that can be used in this
                            where clause.
              relatedObjects - An array containing the list of the GIS features/
                               objects IDs per feature class/table name that are in
                               relation with schematic features in the resulting
                               queried diagrams. Each GIS feature/object ID
                               corresponds to a value of the OBJECTID field in the
                               GIS feature class/table.
              relatedSchematicObjects - An array containing the list of the
                                        schematic feature names per schematic
                                        feature class ID that have the same
                                        associated GIS features/objects with
                                        schematic features in the resulting
                                        queried diagrams. Each schematic feature
                                        name corresponds to a value of the
                                        SCHEMATICTID field in the schematic
                                        feature class.
